PURPOSE: The study contained herein used the database of the American
Board of Colon and Rectal Surgery to demonstrate trends in colorectal
practice from 1989 to 1996 and to compare the one-year technical exper
ience of a colorectal resident with the five-year totals of a general
surgery resident. METHODS: Complete case lists from applicants for the
American Board of Colon and Rectal Surgery's qualifying examination h
ave been entered into a database. Similar data have been compiled from
the Residency Review Committee for Surgery. RESULTS: From 1989 throug
h 1996, 446,082 procedures have been listed by 417 colorectal resident
s, an average of 1,060 cases per resident. When contrasted with the op
erative experience of a general surgery resident, the colorectal resid
ent performs substantially more anorectal operations, more endoscopic
procedures, and more index abdominal operations in one year than the a
verage general surgery resident performs in five years. CONCLUSIONS: W
hen added to the required general surgery experience, one year of trai
ning in colorectal surgery trains a true subspecialist with unique exp
ertise in the treatment of disorders of the colon, rectum, and anus.
